Preventing disruption within information technology environments

ABSTRACT

A determination is made whether an incident that affects one configuration item in a plurality of configuration items within an information technology environment impacts at least one event for at least one other configuration item in the plurality of configuration items. In response to determining that the incident does impact at least one event on at least one other configuration item, one or more pre-defined actions to execute on the at least one other configuration item are identified. The identified one or more pre-defined actions are executed on the at least one other configuration item.

BACKGROUND

The present invention relates generally to the field of information technology (IT) environments, and more particularly to preventing disruption within IT environments.

An IT environment is an integrated collection of technology components that serves the needs of its users and the owner of the resulting system. The complexity of an IT environment can vary widely from simple (e.g., a small business owner with a laptop computer and all-in-one printer/scanner/copier) to highly complex (e.g., a large enterprise with a combination of on-premises equipment and various cloud services such as public, private, and hybrid cloud). There are a number of software tools required for managing the complex IT environments. The functionality of these tools can include, but is not limited to, management of incidents and changes; monitoring for out-of-specification conditions; scheduling; service level agreement measurement tools; performance metrics tools; messaging; configuration management; security; and licensing compliance.

SUMMARY OF THE INVENTION

Embodiments of the present invention include an approach for preventing disruption within information technology (IT) environments. In one embodiment, a determination is made whether an incident that affects one configuration item in a plurality of configuration items within an information technology environment impacts at least one event for at least one other configuration item in the plurality of configuration items. In response to determining that the incident does impact at least one event on at least one other configuration item, one or more pre-defined actions to execute on the at least one other configuration item are identified. The identified one or more pre-defined actions are executed on the at least one other configuration item.

DETAILED DESCRIPTION

Embodiments of the present invention recognize that managing an information technology (IT) environment is a daunting task. Software utilized in an IT environment often comes from several vendors and there may be little to no integration amongst those vendor software packages. This can result in an IT environment that is prone to several risk and technical issues. Further, technical support can be spread amongst specialized teams over widely separated geographic areas. Based on geography, language barriers can occur. This methodology can lead to anything from minor annoyances to major downtime of the IT environment.

Embodiments of the present invention recognize that there may be a method, computer program product, and computer system for preventing disruption within IT environments. In an embodiment, the method, computer program product, and computer system utilize an automated system to share incidents between the various equipment items within the IT environment and coordinating responses in a unified way in response to any incident within the IT environment. Benefits from this automated system include, but are not limited to, faster recognition of incidents by all of the computing devices within the IT environment; reducing the risk of outages of some, or all, of the IT environment; reducing the amount of incident tickets; and reducing coordination efforts between support teams, thereby reducing costs. Another benefit is the streamlining of the technical support required for a complex, world-wide IT environment (e.g., on-premise locations in North America, Europe, the United Kingdom, and Australia, and a mixture of multiple hybrid and private clouds services from several different vendors). This type of complex IT environment encounters difficulties such as language barriers, inconsistencies between various hardware suppliers, incompatibilities between different software programs, different levels of software, etc., and utilizing the present invention mitigates or eliminates these difficulties.

References in the specification to “one embodiment”, “an embodiment”, “an example embodiment”, etc., indicate that the embodiment described may include a particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

The present invention will now be described in detail with reference to the Figures.

According to an embodiment, master server 130 may be one of a laptop, tablet, or netbook personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smartphone, a standard cell phone, a smartwatch or any other wearable technology, or any other hand-held, programmable electronic device capable of communicating with any other computing device within computing environment 100. According to embodiments, master server 130 can be a standalone computing device, a management server, a web server, a mobile computing device, or any other electronic device or computing system capable of receiving, transmitting, and processing data. In other embodiments, master server 130 can represent computing systems utilizing multiple computers as a server system, such as in a cloud computing environment. In certain embodiments, master server 130 represents a computer system utilizing clustered computers and components (e.g., database server computers, application server computers, etc.) that act as a single pool of seamless resources when accessed by elements of computing environment 100. In general, master server 130 is representative of any electronic device or combination of electronic devices capable of executing computer readable program instructions. In an embodiment, computing environment 100 includes any number of master server 130. Master server 130 may include internal and external hardware components as depicted and described in further detail with respect to FIG. 3, in accordance with embodiments of the present invention. In one embodiment, master server 130 includes master event table 132, status message controller 134, and incident program 136.

In an embodiment, master event table 132 is a table of configuration items and associated functions and one or more actions to take upon the identification of an incident for any configuration item within IT environment 120. According to an embodiment, an incident is a planned or unplanned status change to the normal operation of a configuration item. Examples of incidents include, but are not limited to, hardware failure; a database crash; one or more applications stop working; planned maintenance of a configuration item resulting in the configuration item being taken offline for a period of time; network connectivity drops; and the like. In an embodiment, master event table 132 is on master server 130. In another embodiment, master event table 132 is on each configuration item included in IT environment 120. In yet another embodiment, master event table 132 is on each configuration item included in computing environment 100. According to an embodiment, whenever an instance of master event table 132 is updated, all instances of master event table 132 are updated with the same information in real time. In an embodiment, the associated actions included in master event table 132 are based on the specific configuration item and the actual configuration item affected by an incident. For example, if an incident is the planned downtime for a server update, the associated action for a database might be “do not perform backup operations”, the associated action for a job scheduler application might be “hold jobs from running, the associated action for a monitoring tool might be “hold server monitoring”, the associated action for a performance metrics application might be “do not collect metrics”, and the associated action for a jump host or gateway might be to display a messages such as “access to server is denied”.

According to an embodiment of the present invention, status message controller 134 is a messaging module which is capable of communicating with each of the configuration items within computing environment 100, including those within IT environment 120. In one embodiment, status message controller 134 is on master server 130. In another embodiment, status message controller 134 is on each configuration item included in IT environment 120. In yet another embodiment, status message controller 134 is on each configuration item included in computing environment 100. According to an embodiment, messages sent by status message controller 134 include, but are not limited to, the following content: the configuration item or configuration items affected by the incident; and the details of the incident (e.g., what occurred to the configuration item(s), when the incident started, an expected end time for the incident, and an actual end time of the incident). In an embodiment, all configuration items in computing environment 100 can both transmit status messages and receive status messages via status message controller 134.

In an embodiment, incident program 136 can be a program, a subprogram of a larger program, an application, a plurality of applications, or mobile application software, which functions to prevent disruption within information technology (IT) environments. A program is a sequence of instructions written by a programmer to perform a specific task. In an embodiment, incident program 136 runs by itself. In other embodiments, incident program 136 depends on system software (not shown in FIG. 1) to execute. In yet other embodiments, incident program 136 works in conjunction with applications 124. In one embodiment, incident program 136 functions as a stand-alone program residing on master server 130. In another embodiment, incident program 136 works in conjunction with other programs, applications, etc., found in computing environment 100 and IT environment 120. In yet another embodiment, incident program 136 resides on any computing device within IT environment 120. In yet another embodiment, incident program 136 resides on other computing devices (not shown in FIG. 1) in computing environment 100, which are interconnected to IT environment 120 and master server 130 via network 110.

According to an embodiment, incident program 136 receives an indication of at least one incident impacting the normal operation of at least one configuration item. In the embodiment, incident program 136 retrieves and updates the master event table. Further in the embodiment, incident program 136 transmits a warning to each configuration item in the IT environment. Further yet in the embodiment, incident program 136 determines if there are any events on other configuration items that would be impacted by the incident. Further yet in the embodiment, responsive to determining that there are events that would be impacted by the incident, incident program 136 transmits one or more actions to the impacted configuration items as well as the configuration items not impacted. Further yet in the embodiment, incident program 136 receives a notification that the incident has been resolved. Further yet in the embodiment, incident program 136 transmits an update to each of the configuration items. Further yet in the embodiment, incident program 136 receives an update from each configuration item that normal operations have resumed.

FIG. 2 is a flowchart of workflow 200 depicting a method for preventing disruption within information technology (IT) environments. In one embodiment, the method of workflow 200 is performed by incident program 136. In an alternative embodiment, the method of workflow 200 is performed by any other program (e.g., one of applications 124) working with incident program 136. In an embodiment, a user of server 124 invokes workflow 200 upon taking server 124 offline. In an alternative embodiment, a user of server 124 invokes workflow 200 upon accessing incident program 136 on master server 130 via network 110.

In an embodiment, incident program 136 receives indication (step 202). In other words, incident program 136 receives an indication of at least on incident occurring that affects at least one configuration item in an information technology (IT) environment. In an embodiment, an incident is a planned or unplanned status change to the normal operation of a configuration item and the normal operation is the function that the configuration item was designed to perform. Examples of incidents include, but are not limited to, hardware failure; a database crash; one or more applications stop working; planned maintenance of a configuration item resulting in the configuration item being taken offline for a period of time; and network connectivity drops. In the embodiment, a configuration item is any component or system in an IT environment that can be uniquely identified. Examples of configuration items in IT environment 120 include server 121, virtual machine 122, network hardware 123, applications 124, and database 125. Further in the embodiment, the indication includes information concerning the incident, including, but not limited to, the name of the affected at least one configuration item, the at least one incident affecting the at least one configuration item, the start time of the at least one incident, the expected duration of the at least one incident, and a current date and time stamp. According to an embodiment of the present invention, incident program 136 on master server 130 receives an indication of an incident affecting server 121 within IT environment 120. For example, a program on a laptop used by Joe (a server technician for a company) receives an indication of a company server going offline. In the example, Joe has taken the server offline for scheduled maintenance which should last one hour.

According to an embodiment of the present invention, incident program 136 retrieves table (step 204). In other words, responsive to receiving the indication of at least one incident affecting at least one configuration item, incident program 136 retrieves a master event table. In an embodiment, the master event table is a listing of configuration items, associated functions, and one or more actions to take upon the identification of an incident for any configuration item within an IT environment. In one embodiment, the master event table is stored to a central location, such as a master server. In another embodiment, the master event table is stored locally on each configuration item within the IT environment. In yet another embodiment, the master event table is stored to any computing device accessible by all configuration items in the IT environment. According to an embodiment of the present invention, incident program 136 retrieves master event table 132 from master server 130 (which is part of computing environment 100 but not within IT environment 120). For example, the program on the laptop used by Joe retrieves the master event table from its local memory.

In an embodiment, incident program 136 updates the master table (step 206). In other words, incident program 136 updates the retrieved master table with the incident information and then saves (i.e., stores to memory) the updated master event table. According to an embodiment of the present invention, incident program 136 updates the master event table with the name of the affected at least one configuration item, the at least one incident affecting the at least one configuration item, the start time of the at least one incident, the expected duration of the at least one incident, and a current date and time stamp. In an embodiment, when incident program 136 updates the master event table, the event table on each configuration item is updated in real time with the same information so that all configuration items have the same information. In the embodiment, the updated master event table is stored to a memory location (not shown in FIG. 1) after the update is complete. According to an embodiment of the present invention, incident program 136 updates master event table 132, retrieved from master server 130, with the information concerning the incident and stores the updated master event table to a memory. For example, the master event table, retrieved from the local memory of the laptop used by Joe, is updated with the following information: server “2” is offline for scheduled maintenance, the start time of the scheduled maintenance is 8:00 AM, the expected duration of the scheduled maintenance is one hour, and the current date and time is May 3, 2020 at 8:05 AM. Then the updated master event table is stored to the local memory.

In an embodiment, incident program 136 transmits warning (step 208). In other words, incident program 136 transmits a warning message to each configuration item that at least one incident has occurred to at least one configuration item in the IT environment. According to an embodiment of the present invention, the transmitted warning message can be configured in any format known in the art that is understood by all of the configuration items within the IT environment. In an embodiment, the transmitted warning message includes the name of the configuration item affected by the incident, the type of incident (e.g., a software update, an unexpected loss of power, a component change, etc.), the start time of the incident, the expected duration of the incident, and a current date and time stamp. According to an embodiment of the present invention, incident program 136 on master server 130 transmits a warning message, via status message controller 134 on master server 130, to each configuration item in IT environment 120. For example, the program on the laptop used by Joe sends a warning message to each configuration item in its IT environment; the warning message includes the following: a date/time stamp of May 3, 2020 at 8:06 AM, server “2” is offline for scheduled maintenance, the scheduled maintenance started at 8:00 AM and is expected to last for one hour.

According to an embodiment of the present invention, incident program 136 determines whether there are any events affected by the incident (decision step 210). In other words, incident program 136 determines whether any routine (i.e., normal) events for other configuration items are affected (i.e., impacted) by the at least one incident occurring on the at least one configuration item. In an embodiment, an event is a normal operation or function of a configuration item; i.e., the job the configuration item was designed to perform (e.g., a job scheduler schedules jobs for processing, a quality system will monitor metrics of the computing environment, a security tool will monitor for intrusions, etc.). In the embodiment, the configuration item can have any number of events. In one embodiment (decision step 210, NO branch), incident program 136 determines that no events are occurring for other configuration items; therefore, incident program 136 proceeds to step 212 to receive a status. In the embodiment (decision step 210, YES branch), incident program 136 determines that at least one event for at least one configuration item will be affected by the incident; therefore, incident program 136 proceeds to step 214 to transmit actions.

According to an embodiment of the present invention, incident program 136 receives status (step 212). In other words, incident program 136 receives a current status confirming normal operation of each configuration item within the IT environment. In an embodiment, incident program 136 receives a status message from each of server 121, virtual machine 122, network hardware 123, applications 124, and database 125 (i.e., the configuration items within IT environment 120), indicating normal operation. In the embodiment, the status message is routed via status message controller 134 on master server 130. For example, the program on the laptop used by Joe receives a status message indicating normal operation of each configuration item within the IT environment that includes server “2”.

In an embodiment, incident program 136 identifies actions (step 214). In other words, responsive to determining that one or more events of one or more configuration items would be affected by the incident, incident program 136 identifies one or more pre-defined actions to execute on the one or more configuration items affected by the incident. According to an embodiment of the present invention, the one or more actions are pre-defined based on (i) the incident that is occurring, (ii) the configuration item where the incident is occurring, (iii) the configuration item(s) affected by the incident, and (iv) the event occurring on the affected configuration item(s). In an embodiment, incident program 136 identifies one or more actions to execute on the configuration items in IT environment 120 affected by the incident. For example, the program on the laptop used by Joe identifies the following one or more actions based on the “server ‘2’ offline incident”: (i) an action to stop backup operations is identified for the backup/restore configuration item, (ii) an action to hold jobs is identified for the job scheduler configuration item, (iii) an action to stop generating tickets is identified for the monitoring configuration item, (iv) an action to not attempt any operations is identified for the orchestration configuration item, (v) an action to stop collecting data is identified for the metrics configuration item, and (vi) an action to display an advisory message to any user trying to access server “2” is identified for the jump host/gateway configuration item.

According to at least one embodiment, incident program 136 executes actions (step 216). In other words, incident program 136 executes the identified one or more pre-defined actions on the one or more associated configuration items affected by the incident. In an embodiment, incident program 136 executes the one or more pre-defined actions on the one or more associated configuration items itself. In another embodiment, incident program 136 executes the one or more pre-defined actions on the one or more associated configuration items by transmitting an instruction set to each of the one or more associated configuration items and the one or more associated configuration items carryout the instruction set thereby executing the identified one or more pre-defined actions. According to an embodiment, incident program 136 executes the identified one or more pre-defined actions on the configuration items in IT environment 120 affected by the incident. For example, the program on the laptop used by Joe executes the following actions based on the incident of server “2” being taken offline: (i) the program stops any backup operations scheduled on the backup/restore configuration item; (ii) the program holds all jobs scheduled on the scheduler configuration item; (iii) the program stops the generation of tickets by the monitoring configuration item; (iv) the program prevents the orchestration configuration item from initiating any operations; (v) the program stops the metrics configuration item from collecting data; and (vi) the program displays an advisory message on the jump host/gateway configuration item indicating that users should not try to access server “2”.

According to an embodiment of the present invention, incident program 136 receives notification (step 218). In other words, incident program 136 receives a notification from the configuration item where the incident occurred when the incident has been resolved (i.e., completed, fixed, etc.). In an embodiment, incident program 136 receives a notification via status message controller 134 that the incident affecting server 121 in IT environment 120 has been resolved. For example, the program on the laptop used by Joe receives a message from server “2” that the scheduled maintenance has been completed.

In an embodiment, incident program 136 transmits update (step 220). In other words, responsive to receiving the notification that the incident has been resolved, incident program 136 transmits an update to all of the configuration items in the IT environment to (i) return to normal operation and (ii) to update their respective event tables showing the incident as resolved. According to an embodiment of the present invention, incident program 136 transmits, via status message controller 134 on master server 130, an update to each of server 121, virtual machine 122, network hardware 123, applications 124, and database 125 to return to normal operation and to update their respective event tables. For example, the program on the laptop used by Joe transmits an update message to all of the configuration items in the same IT environment as server “2”. In the example, the update message informs said configuration items to return to normal operation and to update their event tables.

According to an embodiment, incident program 136 receives update (step 222). In other words, responsive to transmitting the update to return to normal operation, incident program 136 receives an update message from each configuration item confirming that normal operation has resumed. In an embodiment, incident program 136 receives, via status message controller 134 on master server 130, an update message from each of server 121, virtual machine 122, network hardware 123, applications 124, and database 125 that each configuration item has resumed normal operations. For example, the program on the laptop used by Joe receives from each configuration item in the IT environment with server “2” that each has resumed normal operations.
